Abstract: A three-dimensional numerical model was applied to study the bed morphology and bedload transport of the junction of Ara and Kurau rivers in Perak in Malaysia. SSIIM2 a 3D k-ɜ turbulence CFD model with an adaptive, non-orthogonal and unstructured grid has been used for modeling the hydrodynamic of confluence. The numerical model was tested against field data from Ara-Kurau confluence. Satisfactory agreement was found between computed and measured bedload and bed elevation in the field. The study indicates that numerical models might become a useful tool for predicting the bedload transport rate and bed morphology changes in river confluences.
